  • In this paper, a logic eFuse (electrical Fuse) OTP (One-Time Programmable) memory IP (Intellectual Property) using only logic transistors to reduce the development cost and period of OTP memory IPs is designed. To secure the reliability of other IPs than the OTP memory IP, a higher voltage of 2,4V than VDD (=1.5V) is supplied to only eFuse links of eFuse OTP memory cells directly through an external pad FSOURCE coming from test equipment in testing wafers. Also, an eFuse OTP memory cell of which power is supplied through FSOURCE and hence the program power is increased in a two-dimensional memory array of 128 rows by 8 columns being also able to make the decoding logic implemented in small area. The layout size of the designed 1kb eFuse OTP memory IP with the Dongbu HiTek's 110nm CIS process is $295.595{\mu}m{\times}455.873{\mu}m$ ($=0.134mm^2$).

  • The IPv6 which solved the exhaustion problem of IPv4's IP address is going to be used for many kinds of industries. As a result, there are some products which can be connected to other connectable things, it called Internet of Things (IoT). With growing new propagated products including networking, each product can get an IP address of IPv6, which means it is possible that things also have their own IP addresses. Thus, IP address management system is more important and needs tracking and collecting system for unused products with IP addresses. This study suggests new distribution tracking and inventory management system for IoT products, which offers a current location of things and manages stocks in the warehouse with the static IP address and the location-based service.

  • It is well known that ascorbic acid (VC) is an important factor for several physiological reactions. In the skin, VC works as an anti-aging agent due to removing of oxidative stress generated by UV irradiation and stimulation of collagen synthesis. Thus, developing more effective VC derivatives is an important issue in creating anti-aging skin care products. Our study succeeded to develop a novel ascorbic acid derivative, ascorbic acid tetra-2-hexyldecanoate (VC-IP), which is a lipid-soluble pro-VC. The purpose of this study was to indicate the effects of VC-IP as pro-VC and anti-aging agent. First, it was examined whether VC-IP is converted to VC in physiological conditions. Since VC was detected from the cell extracts treated with VC-IP, it was indicated that VC-IP is a pro- VC.(omiited)

  • $IP^2$(IP based-IMT Network Platform)은 유비쿼터스 플랫폼으로서 백본 망에서 IP 를 IPha(IP host address)와 IPra(IP routing address)으로 두 가지를 사용하여서 이동성을 지원한다. 그리고 MN(Mobile Node)도 Active 상태와 Dormant 상태로 두 가지 상태로 나뉘는데 Dormant 상태에서 상대방이 통신을 요청하면 페이징(Paging) 과정을 통해서 Active 상태로 전이된다. 페이징을 할 때 LA(Location Area)에 속해있는 모든 셀(Cell)에 페이징 메시지를 전송하게 됨으로서 네트워크의 자원을 과도하게 사용하게 된다. 이것을 해결하기 위해서 프럭시(Proxy) 를 두는 방안을 제안하였다. 프럭시에서 MN 들이 존재하는 셀 정보를 유지 함으로서 페이징 요청이 있을 때 정확한 셀에 메시지를 전송하게 되기 때문에 네트워크 자원의 낭비를 줄일 수 있다.

  • The ability of oocytes to undergo normal fertilization and embryo development is acquired during oocyte maturation which is transition from the germinal vesicle stage (GV), germinal vesicle breakdown (GVBD) to metaphase of meiosis II (MII). Part of this process includes redistribution of inositol 1, 4, 5-triphosphate receptor (IP3R), a predominant $Ca^{2+}$ channel on the endoplasmic reticulum membrane. Type 1 IP3R (IP3R1) is expressed in mouse oocytes dominantly. At GV stage, IP3R1 are arranged as a network throughout the cytoplasm with minute accumulation around the nucleus. At MII stage, IP3R1 diffuses to the entire cytoplasm in a more reticular manner, and obvious clusters of IP3R1 are observed at the cortex of the egg. This structural reorganization provides acquisition of $[Ca^{2+}]_i$ oscillatory activity during fertilization. In this review, general properties of IP3R1 in somatic cells and mammalian oocyte are introduced.

  • The mVoIP service is the technology which focuses on the wireless data service as the IP network having the transmission rate of 100 Mbps classes on the high-speed middle of movement through the WiFi, WiBro and 3G mobile radio communication network, and etc. and is developed. Since 2010, the mVoIP (mobile VoIP) service shows the rapid growth due to 4G-LTE service seriously disclosed from July with the Smart phone and 2,011 it begins to be rapidly popularized. In this research, additionally the mVoIP service industry activation plan is presented with the trends of technology development including the chip-set/module/terminal, etc. based upon local and foreign market trend searchlight through the market demand analysis. The mVoIP service downloads App to the mobile apparatus and or can provide the service as the software through the WiFi network. Therefore, the change which is large in the products development aspect is to be have no. Expected to is being provided as the added service in the case of 4G-LTE as a matter of course, the service deployment where it is based on the market principle and demand needs is needed.
